CLOSURE FOR CONTAINERS.

Application filed May 9, 1911. Serial No. 626 001.

lie it known that l. \Yimiirn I'I. l ).\.\'.\'r, :1

citizen of the l'nited States, rrsiding :it Butfalo. in the c untv ofErie and Flute of New Y rk. have lIlHIitttl new and useful lin-])I4Iv'tllll'lll. in Cl sures t'ui' Containers, of which the i'ollmvingis a specification. An object of the invention is to provide a closurefor containers such as milk bottles and the like. ivhcrehv the contentsof the container will he prevented from flowing outyof the same when theclosure in closing position and whereby the closure can be quiclrl} andeasily removed from the container to permit of pouring the contentstherefrom.

To accomplish the desired result, use is made of a \vufer adapted toseat on the upper end of the container to close the opening therein, thesaid Wafer having an inclined slit formed therein, the anguhiriiy' ofthe sides-forming the slit being so arranged that when the container isinverted the contents thereof pressing against one side of the slit willtend to close the slit and prevent the exit of the contents of thecontainer and the said slit being so positioned that a knife blade orsimilar article can be inserted therein and-b means of pressure theclosure can be remd'ed from engagement with the container.

In a large number of the closures no; used on milk bottles and the like,great trouble is experienced in removing the closure from the bottle inthat by exerting a pressure on the closure to remove the samethe'closure is torn or destroyed and it 15 necessary to provide a newclosure for the bottle.

A further disadvanta e in a large number of the closures nowemployedlies 1n the fact: that they do not entirely close the openingsof the containers to which they are ap lied and the contents of thecontainer tend; to leak therefrom. 4

In my device I aim to provide. a simple, eflicient and durable closurewhich-can easily be ap lied to -the container by simply 'ressing t; eclosure into engagement wit the-i container and. which can be qu ick1y're;- moved therefrom-although while positioned v H the. closure exit ofthe contents of the-container. V

Referenocfisfto bahad-to the a'ocom anyldrawingsjconstituting a part 0th1S' catioin'inwhich similar characters of .of "my device a'nd in whichI prevents the reference denote correspondin; parts iii all the views,and in which- Figure l is a fragmentary perspective view of a containershowing my (h-sure applied thereto. Fig. 2 a vertical section takenthrough the clcsnre suhstiinliallv on the line 2-2 in Fig. 1. Fig. I, is:1 plan vieof the modified form of closure. Fig. 4- is a verticalsectional view of the chasm-e shown in Fig. 3.

Referring to the views and more particularly to Figs. 1 and '3, Iprovide a 'wat'crv cap 10 adapted to be positioned over the opening of acontainer 11 to close the same, the said cap being positioned to reposeon an integral flange of the container and "being pressed intofrictional engagement with the said flange so that the contents of thecontainer will be prevented from leakingout between the container andthe edge of the can 10. The cap 10 is provided with an inclined slit 12formed by making a cut in the unitary cap ltl 'so that the sides 13,-1-l-of the slit 12 will extend at an angle to the upper and lQflSUIft1CGS of the jeap 10 as sh wn in Fig.2.;

Now assuming that the container 11 has been filled with a fluid such asmilk or the like and that the. cap 10 has been positioned on thcontainer as mentioned, when the container is inverted the fluid willpress againstthe under surface of the cap 10 thus pressing theside l4 :1ainstthe side 13 and substantially closing t 1e. slit 12 so thatthefluid in the container cannot; flow outwardly throughthe'slit 12, itbein understood that the slit- 12 is of a size equa to the edge of a l,lc'nife blade. When it 1s desired to remove the caplO front thecontainer 11, a, knife blade-1s 'ttngularlyinserted in the slit 12 andby 'pressin downwardly on the outer end of the knife lade or ti-hehandle, thereof, an edge of the cap .nrill be disengaged from thecontainer; and then by pullin upwardly on the k nife" blade against the;s de 13, the -entire cap will be 'diiengaged from the container 'so that;;t;he ontcnts; thereof can be pouredthetefrom' through the opening rormally closed'by'the cap. 4 In Figs-=3 and 4 I disclose a modified-formwafer-y; cap 1 15, substantially 'sim' as f 10 showninFig. 1 and the cap15 is pro- -vi ed with parallel slits 16, 17, having sides -'18 and 19and 20 21 respectively-,the slits lfiand 17 b in formed at ang'angle'tothej jprovide aw i ar to the upper and lower surfaces I i th. :np :indrelslits 16 and 17 heingspeced a night distance 1 apart. By providing-nplurality of spaced slits in the cap 15 the knife blade on he in sertcd1n one of the slits and then bent to 1 extend sligl'ill through thesecond slit so 1 that the cap in its entirety can he. in one movement ofthe knife blade, removed from the container.

It will he understood that should the eontaincr for any reason beinverted when the cap is positioned thereon, the pref-sure of the fluidin the container on the under side of the cap will tend to press thesides 18 and 21 against the sides 19 and '20 respectively, thussubstantially closing the slits 16 and 17 and preventing the exit of thecontents of the container as has been heretofore mentioned in connectionwith the structure shown in Figs. 1 and 2. It will be readily seen thatby disposing the slits at an angle to the hori .zontal planeof the cap,a more efficient derice is provided than would be the result if theslits were provided in the cap at right angles to the horizontal planethereof in that the knife blade or other article would have to beinserted vertically through the slits and the outer end thereof wouldtend to come in contact with the contents of the con tainer while at thesame time any pressure on the cap from either side thereof would nottend to close the slits as is the case when the slits are positioned atan angle relatu'ely to the cap.

Having thus fully described the invention what I claim as new, is a 1. Aclosure for containers comprising a wafery cup for engagement with thecon- 40 minor to normally close the opening thereof, the said cap havingan inclined slit hounded by sides extended at an angle to the plane ofthe cup.

2. ln a closure for containers a wafery cup for engagement with thecontainer to close the opening thereof, the said cap being removablefrom the said container and having a plurality of spaced convergingparallel slits, each of the said slits bounded by 5 parallel sidesextending angularly to the plane of the cap.

3.' A closure for containers comprising a wafery cap for engagement withthe container to normally close the opening thereof, 5 the said caphaving a slit bounded by sides extended at an angle to the plane of thecap with the mentioned sides normally adapted to engage when the cap ispositioned on the contamer.

In testimony whereof I affix my signature in presence of two witnesses.
